We're going to need some more thermo: The value 2270 given for evaporationHeat seems fine compared with some other references if it's in (J/g): However, even of the "1mL water equals 1g" dirty trick is used: There seems to be a genuine error in the value 1.996 used:

It's interesting comparing the environmentTemperature 20 °C with the room temperature 30 °C used under Radiation. Presumably the water that is to be vaporised is initially at a distinct lower environment temperature.
